The 86 light drinkers in the original sample (i.e., those who consumed <6 drinks weekly with no/rare bingeing) are not described in this report because they continued with largely low-risk drinking through follow-up, averaging 1.7 ± .07 SEM drinking days per week, 1.8 ± .07 drinks per drinking day, and 3.1 ± .6 binge occasions per year. They showed primarily sedative alcohol responses (16), and no alcohol response factor predicted their future drinking behaviors or problems because there was little signal or variability in target behavior to detect.
